摘要
采用线性规划方法,以水分生态经济综合指标为最大化目标函数,对北方五省(山西、陕西、宁夏、甘肃、内蒙古)以2000年现状进行农业结构调整,调整后方案可使水分生态经济综合指标提高,对缓解水资源缺乏,提高生态经济效益有明显效果。
The objective function 'water ecology-economy combined index'(WEECI) is applied to linear programming to regulate the agriculture in 5 provinces in North China(Shaanxi, Shanxi, Ningxia, Gansu and Nei Mongol) based on the actual conditions in 2000. The results indicate that WEECI increased after the regulation, which effectively ameliorate the water resource shortage and improve the ecological and economical benefit.
